Mody, we can expose this property to allow for api change at 3.2 3.1
In the meanwhile, u can use something like this to change it programmatically if u must but I dont really recommend it. There are caveats when changing the User.Config programmatically like this:
1. The application can cache properties and their values and I dont know if this is the case with EnableUndo.
2. This code saves the User.Config on disk and this save is not synchronized with the Options dialog or other application code that may be saving the User.Config (which cld lead to a conflict if both try to save at the same time)
internal class ToggleGP_EnableUndo : Button {
private static readonly string GP_EnableUndo = "EnableUndo";
protected override void OnClick() {
var enable_undo = GetGPEnableUndoSetting();
SetGPEnableUndoSetting(!enable_undo);
}
private bool GetGPEnableUndoSetting() {
var config = System.Configuration.ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.PerUserRoamingAndLocal);
var group = config.SectionGroups[@"userSettings"] as ConfigurationSectionGroup;
var gp_Section = group.Sections["ArcGIS.Desktop.Internal.GeoProcessing.Properties.Settings"] as ClientSettingsSection;
var enableUndoSetting = gp_Section?.Settings.Get(GP_EnableUndo);
var rawValue = enableUndoSetting?.Value?.ValueXml?.InnerText ?? "False";
return Boolean.Parse(rawValue);
}
private void SetGPEnableUndoSetting(bool enable_undo) {
var config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);
var group = config.SectionGroups[@"userSettings"] as ConfigurationSectionGroup;
var gp_Section = group.Sections["ArcGIS.Desktop.Internal.GeoProcessing.Properties.Settings"] as ClientSettingsSection;
var enableUndoSetting = gp_Section.Settings.Get(GP_EnableUndo);
//null check...
if (enableUndoSetting == null) {
//create a new value
var element = new SettingElement(GP_EnableUndo, SettingsSerializeAs.String);
var xElement = new XElement(XName.Get("value"));
XmlDocument doc = new XmlDocument();
XmlElement valueXml = doc.ReadNode(xElement.CreateReader()) as XmlElement;
valueXml.InnerText = enable_undo.ToString();
element.Value.ValueXml = valueXml;
gp_Section.Settings.Add(element);
}
else {
//change the value
XmlDocument doc = new XmlDocument();
var sr = new StringReader(enableUndoSetting.Value.ValueXml.OuterXml);
XmlElement valueXml = doc.ReadNode(XmlReader.Create(sr)) as XmlElement;
valueXml.InnerText = enable_undo.ToString();
enableUndoSetting.Value.ValueXml = valueXml;
}
config.Save();
}
}
